Web site HealthWatchCenter offers up 8 common first aid mistakes and myths that make things worse, such as putting butter on burns, placing an object between a seizing person's teeth, sucking out snake poison, and tilting your head back during a nose bleed.

Putting butter, mayonnaise, or ice on a burn is a myth, according to HealthWatchCenter who explains what you should really do and why:

Butter, mayo or other types of grease may cause even more damage to tender skin and pulling clothing or other materials stuck to the burn could damage the tissue or pull the skin off completely.

The correct action is to rinse gently with cool water and coat the burn with antibiotic ointment. If the burn is on a sensitive area of the body such as the face or if there are a lot of blisters, then go to the ER and do not pop the blisters.

You also want to seek medical assistance if a burn completely circles a limb or is larger than your hand.
